IMPROVEMENT IN FURR OW-GAGES FOR FLOWS;

Specification forming part of Letters Patent No. 182,665, dated September 26, 1876 application filed July 15, 1876.

To all whom it may concern:

Be it known that I, BENJAMIN B. Hxwsn, of Morrisville, in the county of Lamoille and State of Vermont, have invented a new and valuable Improvement in F'urrow- Gage for Flows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a side elevation of my furrow-gage, and Fig. 2 is a plan view thereof. Fig. 3 is a bottom view, and Fig. 4 is a front elevation,

of the same.

My invention consists in a furrow-gage or regulator for plows, constructed with a laterally-vibrating draft-bar, avertical crank having a horizontal arm for operating said draftbar, and suitable mechanism for turning said crank, together with certain auxiliary devices, all substantially as hereinafter set forth.

In the accompanying drawings, A A represent the plow-handles, and B the beam, to the under side of which the plow-point, mold board, 850., are to be attached by standards in the ordinary manner. 0 is a standard or post, secured between handles A A, and supporting a cross-rod, c, on which is pivoted a vertical lever, D, of the first kind. end of said lever is secured to the rear end of a shifting-rod, E, which passes through per-' ward end a rack, F, which meshes with a cogwheel, Gr, fast on the upper portion of a ver tical crank shaft, H, which passes down through a perforation in beam B. The lower end of crank-shaft H is provided with a horizontal arm,'I, on which is secured a downwardly-projecting pin, 7:,th2tl3 engages with the sides of slot j-in draft-bar J. Said draftbar is pivoted at its rear end to the under side of beam B, and supported in front by a loop, K, secured to said beam in such manner as to be vertically adjustable, thereby regulating the depth of the furrow. This vertical adjustment is preferably efi'ected by a rod, k, se-

cured to the upper side of loop K, which passes up through beam B, and is screw-threaded on its upper end. This is raised and lowered by means of a nut, k. guideplate, secured to the upper side of beam B, and operating to hold rack F in engagecorrespondingly vibrates the draft-bar, and

when said bar reaches the end of its vibration it is locked against casual displacement by means of the cogged wheel and rack already described.

By reason of the change in the line of draft thereby produced, the plowpoint will be turned more into or from the land, as may be preferred, and the width of the furrow will be correspondingly varied. The maximum width of the furrow'is further regulated by making pin c detachable from 'arm I, and providing two or more holes or other points of attachment in said arm. The operative length of the crank is thereby increased or decreased at will, and also the consequent throw of the draft-bar to right or left.

Various modifications may be made without departing from the spirit of my invention. For instance, the pin may be on the draft-bar and the slot in arm I. Also, an upper horizontal crank arm may be substituted for toothed wheel G, and loosely connected to rod E, rack F being dispensed with. But I prefer the arrangement shown, as it accomplishes all that is accomplished by the one last mentioned, and more besides.

It is obvious that a cam may be substituted for the crank in shifting the draft-bar laterally. i do not, therefore, design to limit my claim to the crank alone, but my invention includes the equivalents thereof.

What I claim as new, and desire tosecure by Letters Patent, is-
